NICMOS Imaging of Infrared-Luminous Galaxies
N. Z. Scoville, A. S Evans, R. Thompson +6
We present near-infrared images obtained with the HST NICMOS camera for a sample of 9 luminous (LIGs: L_IR (8-1000 microns) >~ 10^11 L_sun) and 15 ultra-luminous (ULIGS: L_IR >~ 10…
Radial Color Gradient and Main Sequence Mass Segregation in M30 (NGC 7099)
Justin H. Howell, Puragra Guhathakurta, Amy Tan
It has long been known that the post-core-collapse globular cluster M30 has a bluer-inward color gradient, and recent work suggests that the central deficiency of bright red giants…
Theoretical Black Hole Mass Distributions
Chris L. Fryer, Vassiliki Kalogera
We derive the theoretical distribution function of black hole masses by studying the formation processes of black holes. We use the results of recent 2D simulations of core-collaps…
Hubble Space Telescope Observations of the Oldest Star Clusters in the LMC
J. A. Johnson, M. Bolte, P. B. Stetson +2
We present V, V-I color-magnitude diagrams (CMDs) for three old star clusters in the Large Magellanic Cloud (LMC): NGC 1466, NGC 2257 and Hodge 11. Our data extend about 3 magnitud…
The Evolution of Early-Type Galaxies in Distant Clusters I.: Surface Photometry and Structural Parameters for 53 Galaxies in the z=0.33 Cluster CL1358+62
Daniel D. Kelson, Garth D. Illingworth, Pieter G. van Dokkum +1
Using HST imaging of CL1358+62 (z=0.33) structural parameters are derived for 53 cluster members. We fit integrated r^{1/4}-laws to the integrated S.B. profiles, and fit two-dimens…
Chandra Detection of Massive Black Holes in Galactic Cooling Flows
Fabrizio Brighenti, William G. Mathews
Anticipating forthcoming observations with the Chandra X-ray telescope, we describe the continuation of interstellar cooling flows deep into the cores of elliptical galaxies. Inter…
Cooling Flow Star Formation and the Apparent Stellar Ages of Elliptical Galaxies
William G. Mathews, Fabrizio Brighenti
Observational constraints and theoretical arguments indicate that cooled interstellar gas in bright elliptical galaxies forms into a young stellar population throughout the region…
Constraints On The Delayed Transition to Detonation in Type Ia Supernovae
A. M. Lisewski, W. Hillebrandt, S. E. Woosley
We investigate the possibility of a delayed detonation in a type Ia supernova under the assumption that the transition to detonation is triggered by turbulence only. Our discussion…
The Extragalactic Distance Scale Key Project XXVII. A Derivation of the Hubble Constant Using the Fundamental Plane and Dn-Sigma Relations in Leo I, Virgo, and Fornax
Daniel D. Kelson, Garth D. Illingworth, John L. Tonry +18
Using published photometry and spectroscopy, we construct the fundamental plane and D_n-Sigma relations in Leo I, Virgo and Fornax. The published Cepheid P-L relations to spirals i…
The Evolution of Stellar Populations in Intermediate Redshift Clusters
Daniel D. Kelson, Garth D. Illingworth, Marijn Franx +1
The ratios and absorption line-strengths of distant cluster galaxies can be used to directly study their stellar populations, determine their redshift of formation, their sca…
Distributed Burning in Type Ia Supernovae: A Statistical Approach
A. M. Lisewski, W. Hillebrandt, S. E. Woosley +2
We present a statistical model which shows the influence of turbulence on a thermonuclear flame propagating in C+O white dwarf matter. Based on a Monte Carlo description of turbule…
Dust and Stellar Populations in the Large Magellanic Cloud
Dennis Zaritsky
We present an analysis of line-of-sight extinction measurements obtained using data from the Magellanic Clouds Photometric Survey, which provides 4-filter photometry for millions o…
Optical Observations of the Binary Pulsar System PSR B1718-19: Implications for Tidal Circularization
M. H. van Kerkwijk, V. M. Kaspi, A. R. Klemola +3
We report on Keck and Hubble Space Telescope optical observations of the eclipsing binary pulsar system PSR B1718-19, in the direction of the globular cluster NGC 6342. These revea…
The Evolution of Early-Type Galaxies in Distant Clusters II: Internal Kinematics of 55 Galaxies in the z=0.33 Cluster CL1358+62
Daniel D. Kelson, Garth D. Illingworth, Pieter G. van Dokkum +1
We define a large sample of galaxies for use in a study of the fundamental plane in the intermediate redshift cluster CL1358+62 at . We have analyzed high resolution spectr…
Some Implications of the Anisotropic Distribution of Satellite Galaxies
Dennis Zaritsky, Anthony H. Gonzalez
We examine a possible connection between the anisotropic distribution of satellite galaxies around giant spiral galaxies and the evolution of satellite systems. The observed polar…
Black Hole - Neutron Star Mergers as Central Engines of Gamma-Ray Bursts
H. -Th. Janka, Th. Eberl, M. Ruffert +1
Hydrodynamic simulations of the merger of stellar mass black hole - neutron star binaries (BH/NS) are compared with mergers of binary neutron stars (NS/NS). The simulations are New…
Core-Collapse Simulations of Rotating Stars
C. L. Fryer, A. Heger
We present the results from a series of two-dimensional core-collapse simulations using a rotating progenitor star. We find that the convection in these simulations is less vigorou…
Formation of Low Mass Stars in Elliptical Galaxy Cooling Flows
William G. Mathews, Fabrizio Brighenti
X-ray emission from hot (T = 10^7 K) interstellar gas in massive elliptical galaxies indicates that 10^{10} M_sun has cooled over a Hubble time, but optical and radio evidence for…
Magnitude bias of microlensed sources towards the Large Magellanic Cloud
HongSheng Zhao, David Graff, Puragra Guhathakurta
There are lines of evidence suggesting that some of the observed microlensing events in the direction of the Large Magellanic Cloud (LMC) are caused by ordinary star lenses as oppo…
